METAL-CASTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 633,179, dated September 19, 1899.

Application filed November 11, 1898. Serial No. 696,116. (No model.)

To all whom it may concern.-

Be it known that we, ALFRED M. ACKLIN and WILLIAM J PATTERSON, residents of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metal-Casting Apparatus; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invent-ion relates to conveyers adapted to be used in connection with metal-casting apparatus, and more particularly to that style of casting apparatus in which a series of molds are connected to an endless carrier, the metal being poured into the molds at one end of the carrier and discharged therefrom in the form of pigs when it reaches the end of its course.

The object of our invention is to improve the construction of such apparatus in certain Ways; and the invention comprises the novel features hereinafter set forth and claimed.

To enable others skilled in the art to make and use our invention, we will describe the 2 5 same more fully, referring to the accompanying drawings, in which Figure 1 is a side view of a portion of our improved casting apparatus. Fig. 2 is a plan View thereof. Fig. 3 is a view of one of the 0 links of the endless carrier. Fig. 4 is a section on the line 4 4, Fig. 1. Fig. 5 is an enlarged view of one of the wheels of the carrier, together with a portion of the axle and the protecting device. Fig. 6 is a face view 5 of the protecting device employed on one end of the axle. Fig. 7 is a face view of the protecting device employed at the other end of the axle, and Fig. 8 isa sectional view of the device shown in Fig. 7.

Like letters indicate like parts in each of the figures.

As above stated, the in vention relates to the style of castingapparatus in which an endless-chain carrier has molds connected thereto, the carrier traveling around a suitable framework; but as our invention merely relates to certain novel features in the construction of the carrier of such apparatus we have not deemed it necessary to illustrate such a casting apparatus in full. Accordingly the letter (t represents the links of the faces of the sides of the link and a bolt or rivet 0 passes through said pipe and openings (l, formed in the link. In this way the central portion of the link is suitably braced and strengthened to prevent its sagging or buckling between its ends. These links a are connected up in the manner shown, the axles e passing through the adjoining ends of each pair of links. On the axles e are the Wheels f, loosely mounted thereon and held from outward movement by the linchpins g. The wheels f have the inner boss it formed around the bore or eye, said boss having the annular groove it formed therein. A collar i is secured to one end of the axle by meansof the set-screw2", said collar having the hood k overhanging the upper portion thereof, said hood being arc shape in form and projecting over the boss h in the manner clearly shown in Fig. 5. It is not necessary to have the hood completely encircle the boss, as the protection is only needed from above. By this construction the journals or bearings of the axle are protected from the molten metal or other material, which is liable to be splashed onto said bearings in the pouring of the molten metal or from a sudden jar or jolt of the mold in its passage over the frame, and any material which finds its way onto the boss will be carried off by the annular groove 71/ and drop below without interfering with the working parts of the apparatus. The collart' also holds the links in position and prevents them from bearing against the wheel. At the opposite end of the axle is a similar collar m, this collar, however, being a split collar and formed of metal having the proper amount of elasticity. A bolt it passes through openings in the collar, said bolt' having the nut 17. thereon, by the turning of which the collar is securely clamped to the axle. This collar has also the protecting-hood 0, which projects over the boss on the wheel and in the manner above described protects the'bearings of the axle. The collar 172 has the lugs 0' formed thereon, said lugs when the collar is in position on the shaft entering the open space in theouter link, as shown in dotted lines in Fig. 2. When the collar is clamped securely to the axle and the lugs 1" enter the link in the I molds are bolted to the links by means of the bolts 2%, and they can be readily removed and replaced by new ones when necessary.

hat we claim as our invention, and desire to secure by Letters Patent, is-

1 An endless carrier comprising open links, axles engaging the links, loosely-mounted wheels 011 said axles, collars on said axles, said collars having lugs thereon adapted to enter the links to prevent the turning of the axles, substantially as set forth.

2. An endless carrier composed of open links, axles engaging the links, loosely-mounted wheels on said axles, split collars on said axles, said collars having lugs thereon adapted to enter the links to prevent the turning of the axles, substantially as set forth.

In testimony whereof We, the said ALFRED M. ACKLIN and WILLIAM J. PATTERSON, have hereunto set our hands.
